FASTENING FOR MEETiNG-RAILS OFSASHES.

SPECIFICATION forming part of Letters Patent No. 313,258, dated March 3, 1885.

Application filed December 26, 1894. (No IilOdBll) To all whom it may concern:

Be it known that I, GEORGE THUMsHmN, of Branford, in the county of New Haven and State of Connecticut, have invented a new Improvement in Sash-Fasteners; and I do hereby declare the following, when taken in con nection with accompanying drawings and the letters of reference marked'thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-- Figure l, atop view Showing the parts in the locked position and in broken lines unlocked;

- Fig. 2, a transverse sectional side view; Fig.

3, an under side iew showing the parts in their locked position; Fig. 4:, a top view of the plate and locking lever detached from the base; Fig. 5, an under side view of the two parts separated; Fig. 6, a top view, and Fig. 7 a sectional side view, of the two parts in a modified form;

This invention relates to that class of sashfasteners designed to be applied to the meeting-rails,with the plate on the top of the upper rail of the lower sash, and the keeper on the lower rail of the upper sash, and to that subdivision of this class in which the handle end of the lever is employed as a means for looking the bolt in either the locked or unlocked position-in the first case to prevent interference with the bolt from the outside, and in the second case to prevent the bolt from interfering with the sash in raising or loweringthe object of the invention being a simple construction whereby the parts may be cast and finished by tumbling operation and without mechanical manipulation, and whereby a good and cheap fastener is produced; and the invention consists in the construction as hereinafter described, and more particularly recited in the claim.

A represents the base; B, the pivot standing vertically on the base; C, the locking-bolt hung upon the pivot B as a center of motion, its inner end terminating in an upward projection or hook, D, or other means for engaging the keeper E.

Any of the known constructions whereby the bolt may engage the keeper may be employed. I show one common and well-known construction. At its hub or pivot end the bolt C is constructed with a trunnion, a, projecting from each side at right angles to the line of the bolt.

F is the locking-lever. This terminates at its outer end in a thumb-piece or convenient shape for applying the fingers in turning the bolt. Its inner end is bifurcated, as seen in Figs. 4 and 5. The two branches 1) I) extend, the one to one side and the other to the opposite side of the bolt, and fitted with a seat, (1, to set upon the trunnions, as seen in Fig. 2, and so as to embrace the hub of the bolt. Over the hub portion of the fastener a covering-shell, G, is applied, through which, at the rear, is an opening for the bolt, and at the front an opening, 6, for the locking-lever F, as seen in Fig. 2, the said opening 6 permitting an up-anddown movement of the locking-lever, as indicated in broken lines, Fig. 2.

Upon the under side of the lever F is a downwardly-projecting stud, f, and in the base are two openings, h 1 each corresponding to the stud f. The one, h, is inaposition transversely across the plate through the pivot B; the other, i, is in longitudinal line through the pivot B, as seen in Fig. 3, and so that when the bolt is in the locked position the stud f will drop into the opening h, as seen in Figs. 2 and 3. In that position the bolt is locked, so that it cannot be turned from its keeper until the lever be raised to disengage the stud from its opening h when turned into the longitudinal position, as indicated in broken lines, Fig. 1, and which is the extreme unlocked position. Then the stud f will drop into the opening-i, and there hold the bolt to prevent it being accidentally turned to come into the way of the tion, and so that in such positions the stud on the locking-lever I will readily find its seat in the base.

While I prefer to form the trunnions on the bolt and the seats on thclever, this order may be reversed, as seen in Figs. 6 and'7, by t'orm ing the seat 61 in the bolt C and connecting the arms Z) b with a bar, a, to rest in said seat and form a pivot upon which the lever may rise and fall. I therefore do not wish to limit myself to applying thetrunnions to either the one or the other. By this construction I am enabled to cast the base, keeper, locking-bolt, lever, and the shell G eachcomplete in itself, and so that no mechanical work is required upon either other than that which may be made by the well-known tumbling-barrel, unless it be that the pivot B be tapped into the base. This may, however, be riveted, it pre ferred. The only manual labor required in assembling the parts is that of securi ng the pivot in its place. The fastener is therefore of the cheapest possible construction, and is safely guarded; hence interference from the outside,

or any interfering with the sashes in raising and lowering, is impossible.

The herein-described sash-fastener, consisting of the combination of the base A, constructed with openings hi andwith asegmentshaped slot, Z, the bolt 0, hung upon apivot on the base, and constructed with the stud m to work in the segment-shaped slot in the base, the lever F, constructed with arms to extend each side the hub of the bolt, the said arms and the bolt constructed, the one with a seat and the other witha pivot to rest in said seat, and upon which the said lever may turn in a vertical plane, the said lever also constructed with a downwardly-projecting stud, f, corresponding to the two openings h i in the base, and a shell, G, surrounding the pivot, and having, an opening therein for the bolt, and asec' 0nd opening. 0, through which the lever F will work, substantially as described.
